regret folding?

[bleep]

One of the things I found most frustrating in (online) poker is when the hand I just folded would have been the winning hand. Until I thought of this: At poker sites the cards are selected by a random number generator, which will select different cards at different moments. Even if the flop comes 1/1000th second later or earlier, the cards will be different. Folding and betting will almost never take exactly the same amount of time, so had you not folded, the flop would have been different. Am I right?
